Single-mode fiber (SingleModeFiber): The central glass core is very thin (the core diameter is generally 9 or 10μm), and only one mode of fiber can be transmitted. Single-mode fiber has very small inter-mode dispersion and is suitable for long-distance communication, but it also has material dispersion and waveguide dispersion. In this way, single-mode fiber has […]

The concept of single-mode and multi-mode is the concept of propagation mode of multi-mode fiber and single-mode fiber. The term “mode” is used to describe how the optical signal propagates in the fiber glass core. In a single-mode fiber, light travels along one path; in a multi-mode fiber, light travels in multiple paths. ①Core diameter […]
